Hi,
I'm having trouble compiling code that contains float128 data type.
I'm using MacOS Big Sur 11.4.
Compiler: gcc version 11.1.0 (Homebrew GCC 11.1.0_1)
I have no other problems with Boost, the only problem is when I use float128.
Please note that I have no problem compiling using libquadmath without using
Boost using the __float128 data type.
I use Visual Studio Code:
"tasks": [
{
"label": "Build with g++ 11",
"type": "shell",
"command": "g++-11",
"args": [
"-g",
"-I/usr/local/Cellar/boost/1.76.0/include/",

"-L/usr/local/Cellar/gmp/6.2.1/lib/",

"'-fext-numeric-literals'",
"float128_example.cpp",
"-o",
"main"
],
"group": {
"kind": "build",
"isDefault": true
}
},
There are other libraries (gmp, mpfr, ...) because I have compiled several
examples taken from the Boost site (such as, for example,
automatic_differentation.cpp, GMP_example.cpp, MPFR_example.cpp etc.) and they
all compile and run correctly.
I tried to compile the following example:
#include <boost/cstdfloat.hpp> // For float_64_t, float128_t. Must be first
include!
//#include <boost/config.hpp>
#include <boost/multiprecision/float128.hpp>
#include <boost/math/special_functions.hpp> // For gamma function.
#include <boost/math/constants/constants.hpp> // For constants pi, e ...
#include <typeinfo> //
#include <cmath> // for pow function.
int main()
{
try
{
//[float128_example_3
// Always use try'n'catch blocks to ensure any error messages are displayed.
//`Ensure that all possibly significant digits (17) including trailing zeros
are shown.
std::cout.precision(std::numeric_limits<boost::float64_t>::max_digits10);
std::cout.setf(std::ios::showpoint); // Show all significant trailing zeros.
//] [/ float128_example_3]

std::endl;
#endif

std::cout.precision(std::numeric_limits<float128>::max_digits10); // Show

std::cout.setf(std::ios::showpoint); // Show all significant trailing zeros.
// float128 pi0 = boost::math::constants::pi(); // Compile fails - need to
